The incident ray,____ ray and the ____ at the point of incidence. all on the same plane.

Unpolarized light is incident on a plane sheet of water surface. The angle of incidence for which the reflected and refracted rays are perpendicular to each other is ( mu of water =4/3 )

A perpendicular line drawn at the point of incidence is called the___________ .

The incident ray , the refracted ray of light and the normal to the refracting surface all lie in the different plane .

Two plane mirrors A and B are aligned parallel to each other, as shown in the figure. A light ray is incident at an angle of 30^@ at a point just nside one end of A. The plane of incidence coincides with the plane of the figure. The maximum number of times the ray undergoes reflections (including the first one) before it emerges out is)

The incident ray is along the line 3x-4y-3=0 and the reflected ray is along the line 24 x+7y+5=0. Find the equation of mirrors.

Unpolarised light is incident on a plane glass surface. What should be the angle of incidence so that the reflected and refracted rays are perpendicular to each other? (Given n=1.5)

What should be the angle between two plane mirror so that whatever be the angle of incidence, the incident ray and the reflected ray from the two mirrors be parallel to each other
